Step inside the studio of baseball's greatest sign maker

If you've watched enough A's home games this year, you've definitely seen his work. Amongst the madness in the right-field bleachers sits devoted A's fan and skilled artist Ian Sagabaen, arguably the greatest signmaker in baseball.

He's been featured a couple of times on Cut4 over the past couple of seasons, so we went behind the scenes to see how Sagabaen makes his magic.

From the office of his quiet South Bay apartment, the San Francisco-based graphic designer gets to work on his desktop. They start as ideas, turn into Google Images searches, PhotoShop projects, trips to the local printer and then, voila, super sweet signs.

"Usually I get good reactions," Sagabaen said. "Stuff like this is really fun. Because of this I'm looking forward to every game. It's a really fun hobby and the A's are a good source of inspiration for me."

Another inspiration: fellow Oakland fans, who he interacts with on Twitter (his handle is @Gr8estSignMaker) to get their ideas for good posters before bringing them to life.

Sagabaen's most popular sign since the start of last season has been his Brick Tamland "Let's Go Oakland" declaration, but he also has about two dozen more. From manager Bob Melvin's googly-eyed "Melvinsanity" masterpiece to his handful of Josh Reddick creations to the one equating the bespectacled Eric Sogard to Harry Potter, "the world's greatest sign maker" has something for all tastes.
